Answer: 5

Solution:

Condensation polymers are any kind of polymers formed through a condensation reaction where molecules join together—losing small molecules as byproducts such as water, ammonia or methanol.
Among the given polymers Nylon-6, glyptol, terylene, bakelite and nylon-6,6 are condensation polymers.
